Chapter 9: LPC24XX Pin connect

5.7 Pin Function Select Register 6 (PINSEL6 - 0xE002 C018)

The PINSEL6 register controls the functions of the pins as per the settings listed in

Table 9–138

. The direction control bit in the FIO3DIR register is effective only when the

GPIO function is selected for a pin. For other functions, direction is controlled
automatically.

[1]

For flashless parts LPC2460/70, operates as BOOT0 pin on POR (see

Section 8–6

[2]

For flashless parts LPC2460/70, operates as BOOT1 pin on POR (see

Section 8–6

5.8 Pin Function Select Register 7 (PINSEL7 - 0xE002 C01C)

The PINSEL7 register controls the functions of the pins as per the settings listed in

Table 9–139

. The direction control bit in the FIO3DIR register is effective only when the

GPIO function is selected for a pin. For other functions, direction is controlled
automatically.

The bit functions in this register depend on the number of pins of each LPC2400 part. For
the 180-pin LPC2458, see

Table 9–139

. For the 208-pin LPC2460/68/70/78, see

Table 9–140
